A quest for all 3rd gen 3sgte owners! Options

Hi, I have a little test that I want you to perform on your engine. I want to do it for my personal knowledge, but I will share it with everyone else on this board or on other forum.

I want you to take a timing light, hook it to your engine and note the where is your timing where the engine is idling. Here's the steps to perform the test :

1- Start your engine and let it reach the normal running coolant temp (about 190°F).
2- When the engine is hot, hook up a timing light to the cyl #1 spark plug wire. DO NOT BRIDGE ANY TERMINAL IN THE DIAGNOSIS PORT.
3- Aim the crank pulley and notice what is the timing that the timing light is showing (It may be difficult because there is not a lot of timing reference (the reference is from 20° BTDC to 5° ATDC). I think that the timing should be between 15-25° BTDC.
4- Note what is the current RPM (your idle RPM).
5- If you have an aftermarket boost gauge, note what is the vaccum value when your engine is idling (it should be close of 19 in-hg vaccum)

Post your value on this thread.

This will be very helpful for me and for other people who are trying to build an ignition advance table on their Engine Management system.

Thanks in advance!

Sam

I dont have the tools and my tach meter is not hooked up. I can say that from sound of it my 3rg gen is idling at about 2K rpm. I do have greddy prospec 2 err whatever its called boost controller thing. I also have sprecter EMS all installed by xat racing. My car takes 3 times to start and or I have to keep pumping gas pedal first 20 ish seconds for it not to stall. It just does not like to start at all. When it runs it looks like it runs at about 2000 rpm having a very sexy growl sound. my boost meter reads 58-60 and i think its x100. I do assume normal boost level is around 5-6 even at highway speeds. When I step on gas i seem my gause go as high as 11-12 lbs of boost.
